Effects of Walking Apnea At Low Lung Volume on Hypoalgesia

NCT06638515 | Recruiting

• 1 other identifier: CSEULS-PI-018/2023
• Study Type: interventional
• Target: 60
• Locations: 1 country
• Sites: 1

Brief Summary

The aim of this randomized controlled study is to explore the hypoalgesic response of a 6 minutes of intermittent walking apneas training session at low lung volume in healthy subjects; also, as secondary objectives, to analyze the cardiovascular and respiratory response produced during the intervention.

Conditions

Pain; Hypoxemia; Hypercapnia; Apneas

Outcome Measures

Primary Outcomes (1)

• Pain pressure threshold (PPT) on thumb, anterior tibial and spinous process of C7

  PPT is tested on the dorsal base of the distal phalanx of the thumb on the dominant side and on the muscle belly of the tibialis anterior on the dominant side. The region to be pressed is marked with a pen. The patient is instructed to report with the first appearance of the sensation of "discomfort". An ascending ramp of 0.5 kg/cm/s is applied, at the rhythm of a metronome. The measurement is started on the thumb, and alternated with tibia and C7 until 3 measurements of each region are obtained, enough time to give 30 seconds of rest between measurements in the same region. This protocol has demonstrated high inter-observer reliability measuring healthy subjects (ICC = 0.91).

Study Arms (2)

Walking apnea at Low Lung Volume

EXPERIMENTAL

Participants walk at 6 km/h (10% slope) on treadmill for 6 minutes performing series of intermitent apneas

Other: Walking apnea at Low Lung Volume

Walking normal breathing

ACTIVE COMPARATOR

Participants walk with normal breathing at 6 km/h (10% slope) on treadmill for 6 minutes.

Other: Walking at normal breathing

Interventions

Walking apnea at Low Lung Volume OTHER

Walking apnea at low Lung Volume Participants walk at 6 km/h (10% slope) on treadmill for 6 minutes. Participants in the experimental group will perform intermittent apneas at high lung volume with a density of 5 seconds, followed by a normal breath of 5 seconds until completing the 6 minutes)

Walking apnea at Low Lung Volume

Walking at normal breathing OTHER

Participants walk at 6 km/h (10% slope) on treadmill for 6 minutes. Participants in the control group will remain breathing normally for these 6 minutes.

Walking normal breathing
